Abstract: Disclosed in the present invention is an electromagnetic pump, including: a pump body; an inner iron core, including a central cylinder, an axis of the central cylinder basically coinciding with an axis of the electromagnetic pump; a plurality of outer iron cores, disposed at least partially surrounding the inner iron core; a winding, at least partially disposed on the outer iron cores; and a pump channel mechanism, at least partially disposed between the outer iron cores and the inner iron core, where the pump channel mechanism includes: a first pump channel wall, a second pump channel wall, a circulation channel, and a cavity dividing structure, and being used for supporting the first pump channel wall and the second pump channel wall, the cavity dividing structure being further used for dividing the circulation channel, to divide the circulation channel into a plurality of channels.

Abstract: Methods, systems, and computer programs for identifying, by an operating system, a power consumption level associated with a platform configuration of the information handling system; identifying, by the operating system, a bandwidth associated with a flash memory medium of the information handling system; identifying a first battery charge level associated with a battery of the information handling system, the battery in a charging state; determining a first cache size based on the power consumption level associated with the platform configuration, the bandwidth associated with the flash memory medium, and the first battery charge level associated with the battery; and enabling a first portion of the cache memory based on the determined first cache size.

Abstract: A method for predicting valve leakage, comprising following steps: 1) prefabricating a valve; 2) mounting, on the valve, a sensor (70) and a signal transmitter (90); 3) debugging the valve, measuring and determining a critical specific pressure of a sealing face, and preconfiguring the critical specific pressure into the signal transmitter (90); 4) detecting, by the sensor (70), the specific pressure of the sealing face in real time, and transmitting a specific pressure signal to the signal transmitter (90); and 5) comparing, the signal transmitter (90), the detected specific pressure of the sealing face with the critical specific pressure to determine whether the valve is about to leak, i.e., determining that the valve is well sealed and providing no alert when the detected specific pressure of the sealing face is greater than the critical specific pressure.

Abstract: The present disclosure provides a method and an apparatus for processing resource returning. According to the method, as a first user requests for a return of a resource associated with a prior online trade, a trading server determines if the first user has a user rating greater or equal to a preset user rating threshold, and if yes, returns the requested online trading resource to the first user without waiting until a second user has received the corresponding returned goods or services from the first user. The method can expedite the process of returning resources in online trading, and lightens the system burden caused by the user's frequently refreshing the account to check the resource return status.
